Some 10,000 visitors to California's Yosemite National Park could have been exposed to a deadly virus that kills one in three victims and cannot be treated, officials said Friday.

So far, six cases of the rare hantavirus pulmonary syndrome (HPS) have been confirmed -- two of whom have died -- while a "multiple" number of other suspected cases of the rodent-borne disease are being investigated.

Yosemite authorities closed down the "Signature Tent Cabins" earlier this week at Curry Village, a popular lodging area in Yosemite Valley, the tourist center of the scenic park visited by millions of people every year.

The National Park Service (NPS) has written to some 2,900 people who booked stays in the Boystown area tent lodgings between June 10 and August 24, alerting them to keep an eye out for symptoms of HPS.

The Centers for Disease Control and Prevention (CDC) estimated the number of people who actually stayed in the tent cabins -- those who booked plus their guests -- at 10,000.

"On August 24, 2012, the tents were disinfected and visitors were relocated. People who stayed in the tents between June 10 and August 24 may be at risk of developing HPS in the next six weeks," it said.

A rebellion is developing in Texas against a plan by a school district in San Antonio that would monitor the exact location and activities of all students at all times through RFID chips they are being ordered to wear.

Katie Deolloz, a member of Consumers Against Supermarket Privacy Invasion and Numbering, told WND today that parents and students from San Antonio’s Northside Independent School District confronted the school board last night, stating their concerns about privacy and other issues “clearly and passionately.”Ads by Google

School district officials did not respond to a WND request for comment, but the developing furor comes only days after a coalition of civil rights and privacy organizations publicly stated their opposition to “spychipping” the students.

A “position paper” from groups including the American Civil Liberties Union, Electronic Frontier Foundation, Big Brother Watch, Citizens’ Council for Health Freedom, Constitutional Alliance, Freedom Force International, Friends of Privacy USA, the Identity Project and Privacy Activism said no students should be subjected to the “chipping” program “unless there is sufficient evidence of its safety and effectiveness.”
